<h1>ogg_sync_pageseek</h1>

<p><i>declared in "ogg/ogg.h";</i></p>

<p>This function synchronizes the ogg_sync_state struct to the next ogg_page.
 <p>This is useful when seeking within a bitstream.  ogg_sync_pageseek will synchronize to the next page in the bitstream and return information about how many bytes we advanced or skipped in order to do so.
